Has anyone else had the issue where, after the update, the ringtones and notifications keep changing? I know it sounds like a minor thing, but there have been times in the last week where my phone has been ringing and I didn't know it was MINE. I have different ringtones set for different people, and one specific ringtone set for my notifications - I didn't expect it to keep after the upgrade (and they didn't), so I went back and changed everything back to the way I wanted it - the phone keeps changing the ringtones and notification tone to "Unknown" (not even the default). When I change it back, it'll stay that way sometimes for a day, but it does crazy stuff, like make my default ringtone my default NOTIFICATION sound and vica versa (or make either whatever the heck it wants). PLEASE tell me there's something I can do (this is driving me insane, I'm sick of missing calls and changing everything back to my 'normal') - if I wanted the phone to tell me what my ringtones are going to be, I'd have an iPhone.
